Hi all, up for sale today is my beautiful Must de Cartier Tank Trinity. There are three kinds of gold on the dial (rose yellow and white), and paired Roman numerals it is quite striking. Must de Cartier's origins date back to the early 1970s, when, according to legend, an employee who had been prompted for marketing ideas at a meeting exclaimed "Cartier, it's a must!" This unique philosophy guided the luxury goods company as it sought to create a line of less expensive tank wristwatches that would be more widely accessible. The discoloration on this watch is not due to gold loss, it is actually patina from the vermeil plating. Here is an extreme example: https://www.lot-art.com/auction-lots/Must-de-Cartier-Tank-Vermeil-Quartz-Watch/449-must_cartier-17.6.21-hampton Measuring 23x31mm, this is the larger version ref 681006. This is a quartz watch, with a new battery it is running well. The watch is from 1982, so it is running well for being over 40 years old. This comes with the original box, strap and deployant clasp as seen in the pictures, as well as the manual. You can adjust the deployant to fit your wrist as needed! These are rare and not often seen on this model. https://www.etsy.com/listing/1471195287/vintage-cartier-tank-80s-quartz-trinity - same model $2600 Asking $1399 or best offer - free shipping in CONUS.
